SPEEK/Matrimid blend membranes for CO2 separation

- S-PEEK/Matrimid blend membranes were successfully synthesized for the separation of CO2 from gas mixtures.
- The gas permeability and selectivity values fall in between those of the individual polymers, varying systematically with variation of S-PEEK content in the blend.
- Cross-linked S-PEEK/Matrimid blend membranes showed excellent CO2 anti-plasticization properties.
